Long statement necklace--Abalone MOP, pearl, rock crystal

A cheerful gemstone necklace measuring 4' in length. Makes a soft tinkling sound when it moves. Gemstones include abalone mother-of-pearl hoops; 6mm grey freshwater pearls; and rock crystal beads (they have inclusions, are not glass). Beads and fittings are base metal, not sterling. Wear it as a single layer (can tie in center with a necklace shortener like this https://www.ebay.com/itm/233952120407) or doubled. Was purchased on a Princess cruise a decade ago and joyfully worn a few times. I really like the necklace, but am wearing less bold jewelry these days and need to pare my jewel box. Would love to see it go to a good home. For a statement piece, its neutral colors are surprisingly versatile.
